Soylent 2.0 leaves a sticky white film on tongue for me

Surprised I haven't read anything about this. Does this not happen to anyone else? Whenever I drink a bottle of 2.0 it leaves a sort of white film stuck to my tongue. It comes off fine with a toothbrush, but for this reason I never want to drink Soylent when I don't have a sink and toothbrush handy, which kind of defeats the convenience factor.
